Different types of neurotransmitters
Though the causes are not completely understood, it appears to result from a combination of genetics and environmental factors. Brain chemistry, such as the lowering of serotonin levels, may be a factor, but researchers are still studying the role of serotonin in the brainstem. Migraines are thought to be the result of the activation of a mechanism in the brain, which releases the inflammatory substances around the nerves and blood vessels of the head that causes the migraine. You can tell you have a migraine as opposed to a regular headache because your headache will be:
- Moderate or severe
- On one side of your head
- Aggravated by movement
- Lasting from hours to 2-3 days
If your headache has all of these features, accompanied by nausea and sensitivity to light and sound, you’re probably experiencing a migraine. Hopefully, this list is helpful in avoiding potential triggers and future migraine attacks.
